Dina Asher-Smith reflects on successful World Championships

Great Britain's Dina Asher-Smith reflects on her successful World Athletics Championships performances.

The 19-year-old ran two personal bests to reach the final of the 200m in Beijing and then broke a national record to finish fifth.

Asher-Smith, who was speaking to the BBC's Matt Slater at the opening ceremony of the Sainsbury's School Games in Manchester, says her focus is now on the 2016 Olympics in Rio de Janeiro, where she is expecting a much tougher test.
